Ah, I couldn't be arsed after a couple of links because I got tired copy-pasting the link and then changing reddit.com to https://redlib.kittywi.re/ – my whole IP range is banned from reddit for whatever reason so I can't browse it without redlib even if I was so inclined. Well at least without an account, which I don't have.
Should have figured there's an extension. I try to avoid reddit as much as I can so I haven't looked into redlib extensions – keeping it painful to use means I end up there much less from web searches
